BARRE-LHEAD CONSTRUCTION Herbert E. Thyen, Jasper, ind" assignor to Jasper Wood 'Crafters, Inc Jasper, 11111., a corporation of Indiana flriginal application .October 31, 1947, Serial No. 783,243. Divided and this application October 7, 19.48, Serial No. 53,225

lillaim. 1 This invention relates to a construction for a barrel head, particularly to a "barrel head for a bilge barrel, and is a. division of my co-pending application, Serial Number 783,243, filed October 31,1947.

More particularly, the invention relates to barrel .head construction wherein the barrel head can be inserted freely through one end of the barrel for disposition in a tapered seat provided in the end of the barrel. After the barrel head is positioned in the tapered seat, layers of wood veneer are then positioned above the barrel head, andin engagement therewith, and secured to the upper edge of the barrel to hold the barrel head .in position and thereby prevent its removal from 'thebarrel.

An object .of this invention .is to provide a barrel head construction, particularly 'for a bilge barrel thatis more readily assembled, and wherein, after assembly, the barrel head cannot be removed from the end of the barrel.

.A further object of the invention is to pro- .videa barrelliead construction wherein thebarrel head is disposed in its proper position in the end of a barrel by means of a taperedseat and a cofoperating ledge, and the barrel head is thereafter held in position by means of layers of wood veneer secured to the inside surface of the barrel adjacent the upper edge.

Further objects and advantages will become more apparent upon reference to the accompanying drawings and the following description inwhich: 7

Figure '1 is an elevational view of a barrel 'incorporating the features of the barrel head of this invention.

Figure '2 is a schematic View of" an apparatus in which the barrel heads may be installed in a barrel.

Figure 3 is an enlarged crosssectional view of the upper portion of a barrel showing the manner of installing the barrel head.

Figure 4 is a still :further enlarged cross-sectional view-of the barrel head of this invention to clearly show the glue lines and the tapered seat for "thebar-rel head.

Figure 5 is a partial cross-sectional view of the manner of installing the-barrel head in a barrel. illustrating the usebf high frequency energy for heating the bonding agent between the barrel head and the barrel.

The manner-of installingalhead in thelend of a lbarre1, particular1y a bilge barrel, has involved somewhat of :a .problem to obtain absolute leakproofness and to bond the barrel head to :the

2 barrel. In this invention the barrel headand the end portion of the barrel is constructed in such a manner that the barrel head can readily be inserted into the end .of the barrel :and .be bonded permanently to the barrel.

While this invention is particularly illustrated and. described with reference to the manufacture of a plywood barrel and the installing of a .pl-ywood head in the same, yet .it will be understood that the invention is applicable to barrels that may be constructed in other ways such as from a plurality -of individual staves. Further, the barrel head may be a solid wood member rather than a plywood construction as .shown and described herein.

The principal feature of this invention is that the inner surface of the end portion of a barrel is shaped so that it has a cylindrical portion terminating in a tapered seat, the taperedseatterminating in a ledge. A barrel head is provided with a tapered periphery to engage the tapered seat in the side wall of the barrel, the bottom or inner face of the barrel head engaging the ledge. Oneor more plies of wood veneer are then positioned within the cylindrical portion of the end of the barrel with the ends joined with either a, scarf or butt joint and inengagementwith the inner surface of the barrel and with the upper or outer surface of the barrel head. The barrel head and the layer or layers of wood veneer are then bonded to the barrel and to each other, a suitable bonding agent or adhesive beingprovided for this purpose.

From the foregoing it will, therefore, be apparent that the particular invention herein is-not limited to the use of a plywood'barrel construc tion.

In Figure 1 there is shown aplywood barrel I!) which may be constructed according-to the-method disclosed by C. U. Gramelspacher in Patent No. 2,365,754. The barrel it! is provided with the usual heads H, and'may be provided withmetal bands l2 to protect the barrel during handling. The upper end of the barrel will be constructed as more particularly illustrated in Figures '3 and 4.

The body of the barrel I!) may consist of a plywood. wall ,55, 'orrnay consist of a plurality of .individual wood staves suitably secured together. The end portion of the wall l 5 is provided with a cylindrical portion l5 that extends from the end edge I of the barrel toward the interior thereof. This cylindrical portion I5 terminates in a tapered portion 18 that is in the form of a truncated :cone *with the base portion positioned out- 3 wardly toward the end edge of the barrel. The tapered seat portion terminates in a horizontal ledge I9- which forms a stop to regulate the position of the head.

The barrel head I l is a disc that may be either of a plywood construction, as illustrated, or may be a solid member. The edge periphery 28 of the head II is tapered to cooperate with the tapered seat portion I8 in the inner surface of the wall 55 of the barrel.

II is, therefore, in the form of a truncated cone with the base positioned outwardly toward the end edge of the barrel.

With the barrel head in position, as illustrated in Figures 3 and 4, one or more layers of wood. veneer 2| are positioned between the barrel head H and the end edge I? of the barrel against the cylindrical wall portion [6 of the barrel. These layers of wood veneer are suitably bonded to the cylindrical wall portion It and to the head ll of the barrel, a bonding agent 22 being provided for this purpose.

From the foregoing description it will, therefore, be seen that once the barrel head is installed in the barrel it becomes a permanent part of the barrel, and cannot be thereafter removed.

pared with the cylindrical portion it, the tapered t1;

seat portion 18, and the ledge or stop 59. Ihe barrel head I! is also first provided with its tapered periphery 2!].

The prepared inner surface of the barrel is then coated with an adhesive or bonding agent and the barrel head is dropped into position in engagement with the tapered seat 48 with the inner surface of the barrel head H in enga ement with the ledge i9. One or more plies of wood veneer ii are then positioned within the cylindrical portion 6, a suitable bonding agent being provided between the layers of wood veneer and between the wood veneer and the barrel 2%.

A pressure member is then brought down upon the upper edges of the wood veneer sheets 2i, which at this time may still extend above the upper edge I? of the barrel. This pressure member forces the wood veneer sheets 2i downwardly within the cylindrical portion it of the barrel into engagement with the outer face of the barrel head H to thereby force the barrel head into engagement with the tapered seat is and the ledge l9. Heat is then applied to the wood veneer sheets 2! and to the barrel head i! to bond the adhesive, or the adhesive may be an air drying adhesive.

The pressure applying device may consist of a head 25 that has a downwardly extending annular flange 26 that is adapted to engage the outer surface of the wall NE of the barrel when the head 25 is in the position shown in Figure The head 25 carries a flexible bag 27 that receives fluid under pressure through a pipe 28. The fluid admitted into the interior of the bag 27 may be hot and it may be circulated continuously within the bag 21 by providing a suitable outlet at a position remote from the pipe 23.

With the head it of the barrel and the wood veneer sheets 2! in the position shown in Figures 3 and 4, pressure may be introduced into the The barrel head disc 4 flexible bag 21 to thereby expand the wood veneer sheets outwardly against the cylindrical wall I6 of the barrel ID, the flange portion 26 of the head 25 forming an outer wall form or support for the upper edge of the barrel. The pressure may be retained in the bag 2? until the adhesive material has set, either as an air drying adhesive or under heat as applied through the fluid admitted into the bag 21, or by the use of external heat, such as in a hot room or oven.

An apparatus in which pressure can be applied upon the heads of the barrel during assembly bonding is illustrated diagrammatically in Fig ure 2. The press may consist of a bed 30 which carries a hydraulic motor 31 having the ram 32 extending from the bed of the press.

The press will also be provided with a head 33 which carries a hydraulic motor 34 having a ram 35 extending through the head of the press. The rams 32 and 35 carrying the pressure heads 25 and 25a, previously described. The hydraulic system for operating the hydraulic motors 3! and 34 may consist of a pump 49 which receives fluid from the supply tank 4i through the suction line 42. A pressure relief valve 43 relieves excess pressure from the hydraulic system above a predetermined value.

Fluid is delivered from the pump through the discharge line '54 into the flow control valves 35 and 36. The flow control valve 45 has the service lines A! and 48 which supply fluid under pressure to opposite ends of the hydraulic motor 34 to cause reciprocation of the ram 35. Similarly, the flow control valve 46 is provided with service lines 49 and 59 to control the motor 3i.

The flow control valves 45 and 46 have exhaust lines 5! and 52, respectively, which discharge into the supply tank 4|. The flow control valves 45 and G6 are thus what is termed a four-way control Valve to alternately supply fluid to opposite ends of a hydraulic motor while exhausting fluid from the end of the hydraulic motor opposite to that into which fluid under pressure is supplied, to thus control reciprocation of the hydraulic motor.

The flow control valves and 13 may be operated separately or together. As illustrated in the drawing, a manual control 55 is provided for moving the internal mechanism of the valve to regulate the direction of flow of fluid through it. To supply fluid under pressure into the flexible bag 21, the pipes 28 and 2811 are connected with a source of fluid under pressure, such as the pipe 68, having a control valve BI therein. The fluid supplied may be either gaseous 0r liquid, and may be a hot fluid for the purpose of heating the bonding agent, as previously described.

In Figure 5 there is shown an alternate method of heating the bonding agent between the head H and the wall 15 of the barrel and between the sheets of wood veneer 2|. In this arrangement the pressure applyin device 25 is provided with a metal annular flange 26a, the main body of the pressure applying member 25 either being of insulating material, such as wood or the annular flange 28a may be insulated from a metal -iernber which may form the body of the pressure applying device 25. A thin annular metal sheet 63 is placed between the expansible bag 2? and the inner wood veneer sheet 2%. The metal sheet 53 and the flange 26a are adapted to be connected to a suitable source of high frequency current by means of the electric lines 64 and 65.

After the head of the barrel is placed in assembled condition as shown in Figure 1 and pressure has been applied to the expansible bag 21, high frequency'current will be introduced into the electric lines 64 and 65 to heat the bonding agent and cause it to set. In this case, preferably, a thermosetting resin is used as the bonding agent.

While the device disclosed and vdescribed herein constitutes a preferred form of the invention, yet it will be understood that modifications that fall within the scope of the appended claim are intended to be included herein.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is:

A barrel head construction comprising, a plywood barrel wall forming a side wall of a plywood barrel having an opening to receive a plywood barrel head, said side wall having the inner periphery of the end portion thereof formed to a cylinder to slidably receive a barrel head and terminating in a tapered seat of decreasing diameter relative to said cylindrical portion, a plywood barrel head having a tapered edge periphery cooperating with said tapered seat and slidably received in said end portion, and a ring having an outer cylindrical surface positioned in said end portion between said head and the end edge of said wall in engagement with said end portion and said head to retain said head in said end portion, the contacting surfaces of said ring, said head and barrel wall being secured together by adhesive.
